6 7.3 Intended use. PSA and PSTA electrical insulation tape is intended for use in the construction and repair of electrical and electronic equipment. All tape identified in this CID can be used as general purpose PSA electrical insulation tape. However, some of the tape requires thermosetting when used in its intended application. The following is a list of all tapes covered by this CID and their intended use or application: ACT tape. This thermosetting tape is used in fine and ultra-fine wire applications such as coils, motors, and transformers where good strength characteristics, fine electrical properties, and non-corrosiveness are desired CFT tape. This thermosetting tape is used for hook-up wire, spot bundling, and as armor wrap for harnesses. CFT tape is also used for small motors, dynamotor armatures, generators, and transformer coils where good varnish penetration and high tensile strength are desired EF tape. This tape can be used in cold or warm weather, is solvent and moisture resistant, is ideal for electrical maintenance and waterproofing harnesses, and where high dielectric strength and non-corrosiveness are desired GFT tape. This thermosetting tape is used on heavy-gauge wire motor wrappings, in high temperature locations where other adhesive tapes cannot be used, and for general industrial applications MF tape. This tape is resistant to oils, greases, strong acids, organic solvents, and moisture. It provides high dielectric strength. MF tape is used on very fine wire for insulating connections, as crossover and barrier insulation on small bobbin-wound coils, as a holding layer on stick-wound coils, as an outer wrap on coils, and for transformer and capacitor wrapping MFT tape. This thermosetting tape is resistant to moisture, is highly tear resistant, noncorrosive, and provides high dielectric strength. It is used on very fine wire for insulating connections, as crossover and barrier insulation on small bobbin-wound coils, as a holding layer on stick-wound coils, as an outer wrap on coils, for transformer and capacitor wrapping, for insulating brazed or welded connections, and for hi-low barrier insulation in large size stick-wound and small form-wound coils. It is also used for terminal board pads, anchoring winding tap breakouts, and as an outer protective wrap on transformer coils using medium-gauge magnet wire PCT tape. This thermosetting tape is solvent and high-temperature resistant. PCT tape provides puncture protection from solder burrs and weld spikes. PCT tape is ideal for insulating connections in fractional horsepower and shaded pole motors, as barrier insulation between windings of small bobbin-wound motor and transformer coils, as an outer protective wrap on coils, and for bundling end-turns on small motors wound with fine magnet wire PFT tape. This thermosetting tape is abrasion resistant and has high dielectric strength. PFT tape is used for random wound fractional and sub-fractional horsepower motors, end turn bundling, insulating magnet wire to lead wire connections, anchoring leads and phase insulation. PFT tape is ideal for insulating and holding functions in all types of small dry type transformer, 6

7 choke, reactor, and solenoid coils. PFT tape is used for ground and barrier insulation, anchoring terminal boards and leads, coil end cover insulation, and as an outer protective insulation wrap PF tape. This tape is suitable for continuous high temperature operating conditions. It is solvent resistant, flame retardant, exhibits high dielectric strength, and provides outstanding puncture, tear, and abrasion resistance. Its applications include electrical insulation, capacitor, transformer, and coil wrapping, electronic assembly, and wave solder protection. PF tape is recommended for use as a ground, barrier, and phase insulation in small high-performance torroidal coils and high frequency motors, and for end turn bundling and connection insulation in small motors. PF tape thicker than 2.5 mil is used for heavy duty high temperature applications, such as primary insulation in high-performance flexible wiring boards and heater blanket assemblies, in the pick-up and holding of ferrite cores during wiring into computer memories, and for anchoring leads and terminal boards. Its physical and electrical properties are retained at higher temperatures than any other flexible insulation. This tape can also be thermoset but very little additional insulation resistance is gained. 7.4 Ordering data. The acquisition order should specify the following: a.
